Google adsense team just announced its addition of Google Gadget Ads, according to their blog

These ads are interactive, engaging, and will appeal to your users, simultaneously providing value to advertisers while getting visitors to stick around your site. The end result is that advertisers get more engaged users, users have a richer ad experience, and publishers opted in to image ads may see increased competition for their ad space.

This will only show when you enabled or have an adsense setup to display image ads

While there’s no guarantee that they’ll appear on your site, you can increase the chances that they’ll be shown by making sure you’re opted in to image ads and using one of the image ad formats.

Though this is a good addition to the google ads and a new way or an attracting your site visitor to check out the system but still wondering if how it increase your revenue. What will be the difference on having just the image ads on your site. Will check it out soon enough. Just having problem with my ISP.
